Description Paul Eggleton 2015-05-22 08:59:52 UTC

Scott, could you please add a note to the "Deleting a Task" section of the BitBake manual that points out that deleting a task with deltask doesn't reconnect dependencies? For example, if you have task do_c depending on task do_b which in turn depends on task do_a, and you do deltask do_b, then task do_c's dependencies will not be updated to include task do_a, the result being that do_c may be free to run before do_a. If you wish such dependencies to stay intact you should use the noexec varflag to disable the task instead of deleting it with deltask e.g.:

do_b[noexec] = "1"

Paul, 

I have completed the change iterations.  I will set this to IN PROGRESS REVIEW for now.  If I don't hear back in a week then it will move to RESOLVED.

Thanks, 
Scott

Hi,

Received no feedback so I am moving this bug to RESOLVED and setting the documentation flag to "done."
